Search for Pulsed TeV Gamma-ray Emission from the Crab Pulsar
R. W. Lessard, I. H. Bond, S. M. Bradbury +23
We present the results of a search for pulsed TeV emission from the Crab pulsar using the Whipple Observatory's 10 m gamma-ray telescope. The direction of the Crab pulsar was obser…
Whipple Observations of BL Lac Objects
M. D'Vali, I. H. Bond, S. M. Bradbury +23
Only BL Lac objects have been detected as extragalactic sources of very high energy (E > 300 GeV) gamma rays. Using the Whipple Observatory Gamma-ray Telescope, we have attempted t…
Hour-Scale Multiwavelength Variability in Markarian 421
M. Catanese, I. H. Bond, S. M. Bradbury +36
Markarian 421 was observed for about four days with BeppoSAX and the Whipple Observatory gamma-ray telescope in April 1998. A pronounced, well-defined, flare with hour-scale variab…
VHE gamma-ray observations of Markarian 501
Whipple Collaboration, A. C. Breslin, I. H. Bond +29
Markarian 501, a nearby (z=0.033) X-ray selected BL Lacertae object, is a well established source of Very High Energy (VHE, E>=300 GeV) gamma rays. Dramatic variability in its gamm…
Search for TeV Gamma-Rays from Shell-Type Supernova Remnants
Whipple Collaboration, R. W. Lessard, I. H. Bond +26
If cosmic rays with energies <100 TeV originate in the galaxy and are accelerated in shock waves in shell-type supernova remnants (SNRs), gamma-rays will be produced as the result…
The Flux Variability of Markarian 501 in Very High Energy Gamma Rays
J. Quinn, I. H. Bond, P. J. Boyle +26
The BL Lacertae object Markarian 501 was identified as a source of gamma-ray emission at the Whipple Observatory in March 1995. Here we present a flux variability analysis on sever…
